Which cylinder head would be better for a 402 stroker?

I am Between these two:
Stage 3 ls6 PRC heads
PRC L92 heads

What are the advantages and disadvantages of these?

If it were my motor, it wouldn't even be a consideration. I'd do L92 heads anyday over LS6, if you have a 4" bore. You do. I always forget if it's Thunder or TSP that makes them. Whichever. Call them and ask.

I don't think there are any disadvantages at all, either peak or under curve, to going with the L92s. I could be wrong, though.

Depends on what you want to spend. I'd go with either ETP 225s or WCCH L92s. Cant really go wrong with either.

If you have the money go with ET Heads 240cc, 11-degree heads.

Between the two you have listed, go with the PRC LS6 heads as you can bold a FAST 90 on it. You have to go with an exotic intake if you want to go big horsepower with the L92 heads.

If I could do it all over again I would spend the money and get AFR 225s or a set of ETPs. The L92 heads are good for the price, however, you are stuck with the factory L76 intake or a pricey alternative. Second, their are not really any well tested cams out there with the L92s. The AFRs have been run again and again and cam combo's are out there that are known to produce a lot of power. Hell, if you want to save money even some Patriot Ls6 or 6L heads would be a good idea, you will still have the intake options as well as known cam combinations. I am going to swap the L92 heads/intake towards the end of the summer and probably go with a 6.0L head and a Fast 90 intake. Good lick

Their was an article somewhere that compared L92's with the L76 to the Afr's and a fast and the results were almost dead on. The Afr's and fast made a little bit more hp, BUT you are talking a BIG price diff between Afr's and Fast vs L92's and a L76. The L92's continue to be the best bang for the buck and right there performance wise with all the other high dollar stuff.

I went with the West Coast Cylinder Heads Stage 2 L92 heads. I wanted a nice driver and I got one. I run a small cam and the car drives pretty much like stock.
